Most of the population, although aware of the importance of sunscreen, do not apply it because it is a tedious process, an extra step in the routine, or due to its thick texture. And although invisible sunscreens exist, the latest trend is giving way to solar serums.

Its texture
No white residue or greasy feeling: we have all tried the typical thick sunscreen cream that leaves a ghostly trail and is not pleasant at all. This serum offers an ultralight texture, typical of this type of cosmetic, that melts upon contact with the skin and leaves a very pleasant sensation.

The ingredients that make up its Korean formula
The composition of a cosmetic is its most interesting part. These are the main active ingredients of this solar serum:
- Collagen: provides firmness, improves elasticity, and acts against tired appearance.
- 10 types of peptides: help refine pores and protect against the negative effects of external factors.
- Hyaluronic acid: responsible for providing long-lasting hydration and the beloved glass skin effect.

Frequently asked questions about Biodance solar serum
How much does the solar serum contain?
The bottle is 50 ml.
Can it be used under makeup?
Yes.
Does it protect the same as sunscreens?
The important thing is not so much whether it is a serum or a cream, but that the product has the indicated level of protection and is applied in the appropriate amount. In this case, this serum offers SPF 50 and, being a more fluid formula, special attention must be paid to how much is applied to achieve uniform coverage.
